Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous, pink (yellowish to orange or reddish) colored perennials without chlorophyll, 10-50 cm tall, stout, somewhat pubescent, parasitic on mycorrhizal fungus, fleshy roots form a dense mass that is completely enveloped by the fungus and has no direct contact with the soil. Leaves: Scalelike, the upper ones 10-15 mm long, the lower ones smaller. Flowers: Small, yellowish to orange or reddish like the stems, bell-shaped, petals 4 to 5, oblong, 10-12 mm long, pubescent, distinct, scalelike, tardily deciduous, often saccate (pouched) at the base, the upper ones 5-merous, the lower ones often 4-merous, sepals absent or 4-5, ciliate, spatulate to elliptic, 8-11 mm long, nectary lobes 8-10, (paired), stout, not elongate or curved-cylindric, stamens 8-10, filaments sparsely hairy, anthers horizontal at anthesis, horseshoe-shaped, of equal size, flowers borne rarely solitary or (more commonly) in a raceme, nodding at anthesis, erect in fruit. Fruits: Subglobose capsules, 5-7 mm long, with a persistent style 5-7 mm long, capsules with 4-5 segments, these often deciduous after seed dispersal, thin, without connecting, pinnate, vascular bundles when open. Seeds 0.5-1 mm, mostly membranously winged, numer Ecology: Found on moist to mesic or dry soils, in shady places among pines, firs, and aspens, from 0-14,000 ft (0-4276 m); flowering July-August. Distribution: British Columbia to the Alantic Coast, south to Mexico. Notes: Look for this odd-looking, red, pink, or yellowish plant with pendulous flowers of the same color among tree roots and on the forest floor near damp areas. Ethnobotany: The plant was used in a love potion. Synonyms: Hypopitys monotropa, many others, see Tropicos Editor: LCrumbacher 2011 Etymology: Monotropa comes from the Greek monos, "single," and tropos, "a turn" or trope, "a turning," thus meaning "turned or directed to one side," alluding to the one-sided inflorescence, while hypopithys comes from the Greek hypo, "under" and pitys, "the pine," thus found under pines.
Stems 1-3 dm, often clustered, yellow, tawny, pink, or red, ±pubescent; raceme dense, at first nodding, erect at anthesis; fls 8-18 mm, the lower usually 4-merous, the terminal often larger and 5-merous; sep lanceolate, erect, unlike the basally saccate pet; anthers opening by a single cleft into 2 very unequal valves; style shorter than the ovary; stigma ±villous at the margin; 2n=16, 48. Moist or dry woods, usually in acid soil; interruptedly circumboreal, but not at high latitudes, in Amer. s. to Fla. and Mex. (Hypopitys americana)

Saprophytic on slightly acid humus in dry or moist woods. Infrequent to rare, possibly in all parts of the state. In addition to the counties indicated on the map it has been reported from Cass, Franklin, Hamilton, Marion, Vigo, and White Counties. Usually found sparingly in black and white oak woods. I found it in Clark County, however, as an abundant plant in a low, flat, beech and sweet gum woods where the soil is a hard, white, slightly acid clay. The stigmas of all of our Indiana plants are pubescent.
